Wartook is a small settlement in the Grampians National Park, north of Halls Gap. A reservoir was built in 1887 to provide water to the Wimmera/Mallee and at one time there was a post office and school. Interestingly, further research at the Seismicity of Western Australia website found that an earthquake was felt in Robe, South Australia on May 2, 1899 which was a magnitude 5.3 quake. Robe is about 300kms south-west of Wartook. An article from the South Australian Register can be seen at the following link Robe Earthquake
